New scientific and methodological approaches to the laying of root-related plantings of grapes

Abstract

Relevance. The transition to a grafted grape culture solved the problem of saving viticulture from phylloxera, however, the shortcomings of the grafted culture indicate that the problem has not been completely solved. The article substantiates the importance and possibility of maintaining a root culture of phylloxeratolerant varieties based on the development of innovative methodology and technological foundations for the creation and operation of intensive root plantations using scientifically based biotechnological and physiological methods against the background of phylloxera infection. Hypotheses are proposed and experimental data are presented confirming the possibility of forming root-related plantings of tolerant grape varieties in accordance with the biological characteristics of the grape plant. It has been established that the laying of new plantings with root-related cuttings of phylloxera-tolerant varieties in a permanent place using physiologically active compounds, meets the biology of the grape plant, promotes better plant development, accelerates the onset of fruiting and increases the fruitfulness of bushes, in comparison with traditional technology.
